Spice up your wardrobe with some RGB LED spike-action. Inspired by the incredible work of @bekathwia. Designed for the Adafruit's slow glow RGB LEDs. http://www.adafruit.com/products/679 Print spikes using a transparent or clear ABS or PLA. The bracelet... anything goes! Glue the spikes into the bracelet with superglue. The battery compartment(s) can hold 1, 2, 3, or 4 CR2032 batteries. You'll need to drill a tiny hole through the battery compartment to pass your wires. Wrap wire works really well. http://www.adafruit.com/products/1446
